UM0452 User manual Temperature sensor evaluation board Introduction This document explains the functioning of the temperature sensor evaluation board which consists of the ST72F651 microcontroller, STLM75 and STDS75 as temperature sensors, and NAND Flash. This board can operate in 2 modes: Standalone / external power mode USB powered mode The configuration and operation of the evaluation board in both modes is explained in different sections. To select the desired mode, there is a power selection switch (S1) on the board which enables the appropriate selection. When this evaluation board is connected to the computer through a USB cable it also functions as a mass storage device. The default state of the evaluation board is mass storage mode. It switches over to temperature sensor mode using GUI. Figure 1.
